Hello Mick - 

I think George's advice is sound.  In my work refitting TOUCH WOOD I have
found that not only is nothing in her square anymore, she's barely
symmetrical.   I am doing my best to nudge her toward where perhaps she once
was but in the end I am making things fit as they need to.  Perhaps your
rudder is that way too.
